[This invention relates to a coupling and plings. y y v The primary objectof the vinvention is the 5 provision of ya, coupling of `this character,

wherein sections of a fluid line canvbe detachably joined,without liability of. leakage at the .,juncture, the coupling members of the male andv female type being of novel form, 10 so 'that the 'same can be coupled and uncoupled AWith dispatch and when coupled will insure a fluid-tight joint without liability of leakage at this point. y n

Another object'of the invention is the pro- 15 vision of a coupling of this'character, wherein' the l male and female members inter-fit with eachother and a sleeve detachably joins suchmembers together to 'hold the sections of the pipe in longitudinal alignment, the l0 pipe ysection at one end of the coupling being insertedin one member and made fast there# in, with a portion of the extremity ofthe pipe projected so asto constitute a nose to be received in the other'member beyond the point. of junctureof the members of the coupling, thus insuring a positive non-leaking joint, Vthe membersjof the coupling being of un'iqueform toinsure'ready Connection and disconnection of theY parts of the cou- Plng- M f l A further object vof the invention is the provision of a coupling of thisv character which is extremely simple in it-s'construction, possessing of but few parts adapted to beinterfitted with each other to eect a positive seal tight juncture 'or joint between sections of a pipe line for gas or other fluids, thor'- oughly reliable and efficient yin its purpose, strong, durable and inexpensive to manufac' ture and install. lWith-y these and othery objects in View the invention consists in the features of construe* tion, combination and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawing and Vpointed out in the claims hereunto appended. In'tlie accompanying drawing:

Similar reference characters indicate corresponding parts throughout the several views in the drawing. i

Referring to the drawing in detail, the coupling comprises a ymale member 5, a female member 6, and a locking sleeve 7. rlhe members '5 and 6 preferably are of circular cross section and each yis provided'with a central circularfbore or :passage 8, which align ywith one anothery axially when said members are brought together and joined. j

The male memberhas fitted in its bore 8 a tube orjpipe section 9, the outerend ofsaid member 5 beingcountersunk or recessed as at lO intol which is adapted to be forcedgor otherwise introduced solder 1l which also adheres to the wall of therecess or countersink and to the external surfaceri of the pipe or tube 9 so as tomalre the'latterfast within the male member 5. This pipe or tube 9 at yits extremity ll2 protrudes` beyond the member 5 to telescope within the bore or passage 8 inthe femalemember 6v as is clearly shown in Figure l ofthe drawing. j rlhe female member 6 is providedwith external threaded portions i3 Vand 14C', respectively, at opposite endsl thereof, while the bore or passage 8 for a distance of theouter end of the same is provided with screw threads 15, thesey being internally of the member 6 so that a pipe section can be tapped or screwed within the said female member 6. lf desired this. female member can be tapped or screwed into the pipe in the use of the threads as will be clearlyunderstood. yLoosely surrounding the male member 5 is the collar which is formed lat one end with an inwardly extending annular liang'e` le adapted to abut an external annular shoulder 17 formed on the male member 5, the shoulder 17 being confined Within the sleeve or shell 7, Which is provided With internal screw threads 18 to coact With the threads 15 on the female member, so that both the male and female members 5v and 6 Vcan be detachably connected together in the use of the couplinv as is clearly illustrated in Figure 1 of the raWing.

The male vmember 5 at its, juncture end With the female member 6 is formed with a substantially semi-spherical shaped head.v or tip 19 which isadapted to'be're'ceived into a correspondingly shaped seat or recess 20 formed inthe femalemember 6, at the juncture end thereof.

l Adapted tobel carried by the tip or head 19 is a Vcompressibl'e Washer 21 shaped oorrespondingly to the tip or head so that on the joining of the male and female members 5.` and 6, the said. YWasher 21 can be compressed at the juncture terminals of. these members when coupled together4 so as to pro- Vide. Huid-fish@ joint therebetweenrIhe sleeve'or collar 7 is formed With an externally deformed surface 22 so that it can befmanually turned` for the coupling of the members 5 and 6 or the disconnection thereof-With kthese Without liability of the'slippage of thehand or implement as appliedV to the collarv or sleeve.

Inliigurei'of the, drawing there is` slioxvn a slight [modification 'of 4the invention, wherein the recessed endr 23, of the male member 5 is internally threaded. at 24, for the adjustable engagement therein, of a screwl plug 25 which compresses` the solder 11, in this instance being paste metal' and air hardened,'within the'1eCAe SS,-23.y This plug 25y iS formedv latfits outer end'with finger knots 26?, 'whereby it naar be manually turned in and.y out'of the` male member '5L Saidjplug 25 is also. provide'dfwith a centrali passage 27, to accommodate the tube 9, so thatthe plug 25' ivillfencircle lthe latter. i By compressing thelsolnderllV of the paste character it will be caused to adhereto the tube' and `Within the recessin the male member, thereby rendering these partsy unitary,

In the use of the coupling, itiszunderstood that' the pipe sections are joinedfto thein'ale and, .female members V5 6, and these members arel brought together in alignment vvitliu eachfotherfthe sleeveor 'collar '7 is rotated Vin a directionto screw upon the female member 6 and by theivorling of the collar or sleeve home these members are united together to effect a fluid-tight joint therebetweeny .by sealing the juncture between the'head 16 and the seat 20 on and in the male and female members 5 and f6, respectively.

Erom the foregoing it is thought that the construction and manner of operation of the device Will be clearly understood and therefore a more extended explanation has been omitted.
